Differences In Postoperative Levels Research Articles

Evaluation of Serum Metal Ion Levels in Dental Implant Patients: A Prospective Study.

Introduction:Titanium is the most commonly used bio-inert implant material. Nevertheless, there is a possibility of systemic release of metal ions, which could have clinical implications like implant failure and toxicity. This prospective study focuses on the evaluation of serum metal ion levels in patients receiving dental implants. The aim of the study is to evaluate the release of titanium, aluminium, and vanadium from dental implants by comparing the preoperative and postoperative serum levels of these ions.Methodology:Serum samples were collected from 30 patients undergoing dental implant placement preoperatively and postoperatively at intervals of 6 weeks, 3, 6, and 12 months. These samples were analyzed for titanium, aluminium, and vanadium levels using Inductively Coupled Plasma Optical Emission Spectrometry. The difference in preoperative and postoperative serum levels was measured and statistically analyzed using the paired t-test.Results:There was a slight difference in the postoperative levels of titanium and aluminium (2.30 and 4.07 mg/dl) as compared to the preoperative levels (2.28 and 2.30 mg/dl), which was statistically insignificant (P > 0.5). The serum levels of vanadium were too insignificant to be detected by the instrument (<0.0088 mg/dl).Discussion:Mild increase in the titanium and aluminium levels in blood serum was noted. These metallic ion levels might increase significantly due to which further clinical research with larger sample sizes and a long-term follow-up period is required to evaluate the clinical effects of metallic ion release from dental implants. There is no significant difference in the serum metal ion levels before and after the implant placement, although a little increase is observed in the aluminium ion levels after the implant placement.

Comparison of postoperative satisfaction between ulcerative colitis patients who chose to undergo either a pouch or an ileostomy operation

The aim of this study was to investigate differences in postoperative levels of satisfaction regarding current activities, interpersonal relationships, and body image of ulcerative colitis patients who had chosen to undergo either a pouch or an ileostomy operation. In addition, we hypothesized that patients who showed greater fear of bodily damage would choose the pouch operation. The same surgeon carried out all the operations. Follow-up periods varied between 3 months and 10 years. We contacted patients and asked them to complete a questionnaire and return it by mail. Similar numbers of patients from both groups reported satisfaction with their operation, suggesting that patient involvement in the choice of operation is an important factor in postoperative satisfaction. As predicted, fear of bodily damage discriminated between the groups.
